The DARPA Quantum Network

The world's first quantum cryptographic network is now operational beneath
the streets of Cambridge, Mass., providing an extremely secure Virtual
Private Network (VPN) between the campuses of Harvard University, Boston
University, and BBN Technologies. Unlike conventional cryptography, our
system bases its security assurances on the Heisenberg Uncertainty
Principle, transmitting key material modulated onto single photons. This
talk will introduce quantum cryptography (more properly Quantum Key
Distribution) and describe the DARPA Quantum Network in some detail, with
particular emphasis on its unusual networking aspects.

Mr. Elliott has led the design and successful implementation of a number of
secure networks based on novel Internet technology for the United States,
Canada, and the U.K. and has acted as senior advisor on a number of
national and commercial networks including three LEO satellite
constellations and Boeing's Connexion system. Mr. Elliott has particular
expertise in wireless Internet technology, mobile "ad hoc" networks,
quality of service issues, and novel routing techniques. At present he is
leading the design and build-out of a very highly secure network protected
by quantum cryptography. He holds over 125 patents pending or issued on
network technology.
